After the operator considers that the pan has been sufficiently flushed, he closes the valve 27 and since the water no longer acts against the underside of cup 23, said cup descends, closing valve 16 and opening valves 21. Thereupon the water standing in pipes 11, and 12, flows out of said pipes through openings 7, to fill the pan, and water flows through the tubes 19 around the rods 18, also to fill said pan. The openings 7 act as an air vent for the tank until the water in the pan rises to the level of said openings which is also the level of the lower ends of the tubes 19 and the level of the bottom of the tank. Thereafter, no air can get into the tank and, consequently,ithe water will cease to enter the an. Thereafter,-the device will act upon the arometric principle, as the poultry, or animals, use the water from the pan, by drinking the same from the circumferential path between the outer side of the tank and the pipe 6. To prevent the poultry, or animals, getting bodily into this space, wires 29 are pro* vided, which extend between the outer wall of the tank and the outer edge of the pan, and, preferably, these wires are provided with eyes 30, which are strung upon a circumferential wire 31, the outer ends of the wires resting upon the outer edge of the pan.

The drain pipe 15is, preferably, provided with an overflow pipe 32, so that if the tank should become punctured, or an air leak in the pipes should develop, the water cannot rise above the level of theouter edge of the pan, but, on the contrary, would first escape through the drain pipe 32. The bottom of the tank may be provided with a cavity 33, for the upper end of the drain pipe, if desired;

By disconnecting the unions l1 and the union 28, the tank with its valve mechanism 23 and associatedparts, may be lifted free of the pan.

From the foregoing description, it will be seen that simple and eflicient means are herein provided, whereby substantially all labor incident to watering small stock, is eliminated, it being only necessary for the operator to open and close thevalve on the supply line. By doing this, the structure is first flushed and cleaned and thereafter automatically acts, as described, to maintain a clean, fresh supply of water.

It is to be understood that the invention is not limited to the precise construction set forth, but that it includes, within its purview, whatever changes fairly come within either the terms or the spirit of the appended claims.

Having described my invention, what I claim is:

1. A device of the character described comprising a tank and a pan, a drain outlet from the pan, a drain valve controlling said outlet, a water supply pipe and a water pressure operated valve operated by the water from said pipe, which controls said drain valve and the passage of water to said tank and an overflow pipe having its mouth disposed in said tank and discharging into said pan.

2. A device of the character described, comprising a pan, deepest at its central portion, a tank disposed thereabove, an annular pipe extending around the outer edge of said pan and perforated for the discharge of water taiwentially thereof, a pipe connected to said annular pipe and constituting an overflow pipe for the tank which terminates adjacent the top of said tank, a discharge outlet at'the central portionof said pan, a valve for controlling said discharge outlet, a water supply pipe projecting upwardly into the tank, a. member of inverted cup shape slidably mounted upon the upper end of said water supply pipe, and connections between said member of inverted cup shape and said valve, upward movement of said cup shape member permitting the entry of water to the tank, said upward movement being under the influence of the water discharged through the water supply pipe, and means fol-permitting the escape of water from the tank to the pan when said cup like member is relieved of the water-pressure through said supply pipe, the filling of the tank flushing the pan by the overflow of water from the tank,and the shut-ofl of the water permitting the flow of water from the tank to the pan until the openings in the annular pipe are covered, and the passage of air to the interior of the tank is thereby stopped, after which the tubes act upon the barometric principle to maintain a supply of water in the pan.

3. A structure as recited in claim 2, comprising a drain pipe "leading from the discharge open'ing of the pan, and an overflow pipe leading from said drain pipe into the pan and to a point'slightly above the openings in the annular pipe. i

4. A structure as recited in claim 2, in combination'with unions in the overflow pipe and the Water supply pipe to permit the bodily removal of the tank and associated parts from the pan.

5. A structure as recited in claim 2, in combination with wires extending between the side of the tank and said annular pipe.

6. A structure as recited in claim 2, in combination with a plurality of wires strung upon a circumferential wire and extending from the side of the tank to and resting upon the outer edge of the pan.

7.'A. device of the character described, comprising a tank, a pan, and elements upon whi'chthe tank is supported, a circumieren} ti-a1 perforated pipe extending around :the h f upper outer edge of thepan, a discharge opening centrally of the pan,'a drain plpe leading from thedischarge opening, a drain valve for closing said discharge opening and. water supply pipe extending upwardlyinto the tank, a member of inverted cup shape from the drain pipe upwardly'into the pan y and terminating slightly above the level of slidably mounted upon said supply pipe, said supply pipe having openings in the side thereof, which are uncovered by the upward movement of said cup'like member under the influence of the water flowing-from the supply pipe, rods connected to said cup like member and extending downwardly, tubes secured to and extending above the bottom of the tank, through which said rods pass, valves upon said rods for'closing the lower ends of said tubes, a cross bar carried by the said rods and to which the discharge valve is connected, and-overflow pipes extending upwardly from the annular pipe and termi nating in an extension which, inturn, terminates adjacent the top of the tank as and for the purposes set forth;

8. A structureas recited in-claimW, in

combination with an overflow pipe leading the openings in thecircumferential pipe. 9. A structure as recited in claim 7, wherein the openings in the circumferential pipe are so disposedas to dlscharge water tangentially of the pan.

10. A device of the character described, comprising a drinking panpa barometric tank associatedtherewith, a drain valve for v the pan, a source of water supply for the barometric tank, means for automatically operating the drain valve when the water is turned onto fillthe tank and means for sup plying a limited amount of water to the drinking pan after the water supply to the tank is cut ofi.

In testimony whereof I affix my signature. l
